Just wondering what to do with the ARB settings to reduce understeer.
After being in the car today we realized something needs to be done to reduce it!
It's even worse on the track...
Cheers,
Jamie.

Not bothered about drifting... It's not the fastest way around a corner.
You could fiddle with the tyre pressures, I get less understeer in my e46 if I put the same amount in all round.
Stiffer rear ARB should help too

Get rid of the Barry rims Jamie.
Purchase a set of wheels that are more track orientated

stiffen the rear arb and soften the front (assuming you have adjustable ones) and modify driving style. the only time i've had severe understeer is from piling into a corner way too fast and just scrubbing the front wide. get it settled properly into a corner and it's neutral to slightly oversteering.
when was the geometry last checked, and what settings were used? what offset are the wheels, and how do the tyres look? if theyre scrubbing on the outside add a touch of toe out and a little camber to get more of the tyre dealing with the loads.
a road car setup is usually going to be a compromise on track (or vice versa) as the camber you need to cope with roll and soft sidewalled tyres on track will soon kill a set of tyres at more sensible road speeds.

before you mess around with any of the above mentioned 'fixes' you need to fully measure the settings around the whole car using wire & levels etc.
start from checking all tracking, camber, toe, pre load & corner weights etc.
when you got these set correct then the car will be balanced.
theres far more to it than changing bits blindly, all cars are different

Don't you wish there were a knob on the TV to turn up the intelligence? There's one marked 'Brightness', but it doesn't work.
As above soften the front end. Personally Id leave the rear as it is. The idea is to get more weight transfer over the front end when braking, which improves mechanical grip and allows the car to turn.
Alternatively put a turn or so on the front wing
Thats with a proviso though. If your driving style induces udersteer then no amount of tweaking will cure it all. Theres a limit to any car. (defined by basic suspension points, engine poisition, wheel size - particularly if your rear tyres are wider than the front and so on) Depending on how far your father wants to take it he might consider running the GRP A spec lower suspension set up. (Check Gustaves site)
But as a relatively cheaper idea he may wish to spend time thinking about the lines hes taking.

Don't think he will want to fork out for a group A suspension setup 
I think a play with tyre pressures and ARB settings is what it needs at the next track day.
Not sure what ARB's are fitted.. TBH don't even know if they're adjustable...
I would say my dad's driving style is something to do with it he does throw it in corners a bit hard...
Will reducing to 17's help?
Not sure about all the alignment, what would make a good track setup?

if he slows down a bit on entry speed on track he will be able to tell alot more about how the car naturally wants go. straight on or rear end first!
any road car understeers when entry speed is too quick imo.
